FLINT, MI -- Federal authorities in Flint have raided two businesses after they claim they were part of food stamp fraud schemes that cost the government millions of dollars.

Criminal complaints were filed in Flint U.S. District Court over allegations of fraud at Shorthorn Meats on the city's north side and the Downtown Food Store inside the Mass Transportation Authority station in downtown Flint.

Federal authorities claim the suspects would purchase food stamp benefits from undercover officers and confidential informants sent into the store as part of the investigation.

The undercover officers and informants would typically receive cash in the amount of roughly half the original transaction value, according to court records.

Despite the raids, the USDA claims rates of illegal trafficking of Supplemental Nutrition Assistance Program benefits fell to roughly one cent on the dollar in 2006-2008.

Here's a look at other recent food stamp fraud cases around Michigan:
